I am unfortunately very let down by this Stans sealant injector. A poor seal on the plunger leaded to a poor vacuum so it is not very effective and pulling up sealant and then doesn't hold it well. When you remove the hose from the bottle about 1/4 of the sealant leaks out.
Once the hose is on the valve, it is effective at pumping the sealant into the tire, but it's a mess to get to that point.
Overall a disappointment that I wish I hadn't purchased.
I give it two stars because of you can face the mess and wasted sealant, it is effective at inserting sealant in the valve. Marginally better than the 3oz bottles cone cap, but better.
